As the nation gears up to commemorate the 50th anniversary of the first moon landing this month, space enthusiasts and casual visitors can see an artifact from the Apollo 11 mission somewhere unexpected in Northwest D.C.

A rock plucked from the moon’s Sea of Tranquility is embedded in the Washington National Cathedral’s Space Window. Head down the church’s main aisle, and it’s about halfway down on the right.

“We’ve had the rock since 1974,” said National Cathedral archivist Elody Crimi. “The rock itself is about 2 3/8 inches wide and weighs 7.18 grams.”

The cathedral’s display of the moon rock serves to incorporate stories of faith and American ideals and aspirations.

“President (Richard) Nixon was so delighted to grant a rock to the cathedral, also so it could serve as a shrine to the courage of man in the exploration of space,” Crimi said.

There’s a fun fact related to the window you might not hear elsewhere: All the cathedral’s windows used to be plain panes of glass that were changed out with stained glass creations as themes and designs were selected.

What’s commonly known now as the “Space Window” is the 13th design that was up for consideration as artists and church leaders went back and forth deciding what image would best depict the themes of science, technology and space. By the 12th round of negotiations, the artist had had enough.

“They wanted rocket ships, and this and that, and there was too much stuff in the window,” said Kevin Eckstrom, cathedral director of communications. “So, finally (artist Rodney Winfield) said, ‘I’m going to do an artistic representation.’ He showed it to them, and they said, ‘Yup. That’s exactly what we want.'”

The window was installed in 1974 while the cathedral was still under construction. When the building’s nave was completed and the national treasure could be appropriately secured, the moon rock was added to the stained glass window in 1976.
